The mcuboot imgtool uses the python module `cbor`. An equivalent and updated package `cbor2` requires Python 3.7 or newer. The arch packages provide a package `python-cbor2`, but no package for `cbor`. This patch makes it possible to use the system package by adding support for the `cbor2` package additionally to the `cbor` package.
